WEFT-CARRIER MAGAZINE.

Original application filed July 18, 1921, Serial No. 485,420. Dividedand. this application filed April 28,

1924. Serial No. 709,410.

To all whom it may concern:

Be it known that I, EPPA I-I. RYoN, a citizen of the United States,residing at Pasadena, in the county of Los Angeles and State ofCalifornia, have invented a new and useful eft-Carrier Magazine, ofwhich the following is a specification.

This application is a division of Serial No. 485,420, filed July 18,1921, and relates to certain improvements in weft carrier mega zines asapplied to weft replenishing looms, having for its object the provisionof a magazine of simplified construction and very reliable operation.

This application relates particularly to an improved weft carrierreleasing device, which in its preferred form comprises a bobbin supportyieldingly mounted on a pair of parallel links by which the support isguided outward and upward to successive parallel positions.

My invention also relates to certain arrangements and combinations ofparts which will be hereinafter described and more particularly pointedout in the appended claims.

A preferred form of my invention is shown in the drawings in which- Fig.1 is a side elevation of a magazine embodying my improvements, and

Fig. 2 is a partial rear elevation looking in the direction of the arrow2 in Fig. 1.

Referring to the drawings, I have shown parts of a magazine comprisingan end frame 10 connected to a second end frame (not shown) by crossrods 12, 12 and 13 (Fig. Vertically extending flanges 14 on the endframe form separate vertical passages or compartments in which stacks orrows of weft carriers may be assembled.

The lowermost weft carrier of each stack rests upon a support or slidesimilar to those shown in my prior Patent No. 1,005,821, issued October10, 1911, and by which the weft carriers are relatively released uponindication of weft exhaustion. Vertically disposed guide rods 31 and 32outside of the magazine end frame 10 prevent entanglement of the weftends as the weft carriers are fed downward in the magazine.

My present invention relates particularly to improved devices foryieldingly supporting the tips of the bobbins or weft carriers. Thesedevices comprise guide members or supports 33 each mounted on parallellinks 34 and 35. The links 84 are pivoted at 36 on the frame 10 and thelinks 35 are loosely mounted on the cross rods 13. Coil springs 37encircle the rods 13, one end of each spring being secured in the hub ofa link 35 and the other being secured in a collar (not shown) on the rod13 and by which tension of the spring may be adjusted. An adjust ingscrew 39 in the link 34 acts as a stop for the weft carrier support byengagement with a shoulder 40 on the frame 10.

The two supports 33 are similarly constructed and are mounted to bemoved apart as a weft carrier is forced downward by the ransferrer 41.Either of them may also be forced further back to the dotted lineposition shown in Fig. 1 if a weft carrier fails to be properlytransferred and is caught by the shuttle when only partially inserted.The parallel links cause the guide plates 33 to maintain their originalangular relation as they are separated.

In this way, a support 33 is moved quickly upward out of the path ofmovement of a misplaced weft carrier and easily clears the weft carrierwithout damage to the support or to the weft carrier.

Having thus described my invention, it will be evident that changes andmodifications may be made in my invention within the spirit and scopethereof as set forth in the claims and I do not wish to be otherwiselimited to the details herein disclosed but what I claim is 1. In amagazine, a support for the tip of a weft carrier, means to positionsaid support and to guide said support outward and upward tosuccessiveparallel positions and to prevent displacement of said supportfrom parallelism, and means to yieldingly return said support tooperative position.

2. In a magazine, a support for the tip of the weft carrier, a pair ofparallel links on said support, and a spring to yieldingly hold saidsupport in operative position.

In testimony whereof I have hereunto affixed my signature.

EPPA I-I. RYO N.
